Ask yourself, Should I use AdWords? If you are in an industry paying big bucks for the most expensive Google AdWords keywords, you will want to make sure you are implementing pay-per-click marketing best practices. Here are a few to keep in mind:
  • Quality Score: High AdWords Quality Scores can lower your CPC and help you pay less for the most successful keywords. Finding the right keyword niches and dividing large keyword lists into smaller, more segmented lists that you can easily write targeted ad text for, resulting in improved Quality Scores and better keyword rankings.
  • Be Specific: Target specific, 3-5 word keywords. You can use a Google AdWords keyword tool to come up with specific keyword ideas, both broad and long tail keywords.
  • Use Negative Keywords: Irrelevant keywords result in costly clicks that will never drive conversions, and when bidding on the most expensive keywords at $50 per click, negative keywords are absolutely essential.
  • Focus on Relevancy
  • Landing Page Optimization: While most AdWords conversion rates stay around 2%, we will often see landing pages convert at 20% or even 30%. The key to landing page optimization is to continuously try out different types of offers and test how people respond to them.
